(o1. 27o-av) 10 Claims.

My invention is a method of reinforcing the printed sheets or covers of magazines or the like, at their engagement with the staples, which hold the same together, and the product produced by the method.

The ordinary magazine includes a cover and a number of superposed leaves. Both the cover and the leaves are usually printed on both sides. Both the cover and the leaves are formed of continuous paper sheets which are folded transversely upon themselves and are secured together adjacent to the folding line by staples.

It not infrequently happens that the cover is torn from the body of the magazine, or individual sheets are torn from the magazine, by the lifting of the magazine by the cover or the individual sheets, or by other manipulation.

In accordance with my method a reinforcing coating is applied or printed upon the cover sheet and the leaf sheet or sheets, at proper positions thereon. The coating provides coated reinforced area or areas, at the folding lines of the sheets which areas are stronger and tougher than the sheets alone, and the staples pass through these reinforced coated areas. The result is that the cover sheet or leaf sheet or sheets are more securely held in place by staples. The coating material used is one which may be applied to the sheet or sheets by a printing process during the printing of the magazine and therefore must set rapidly. It is preferred to use a. thermoplastic material as a coating, although a rapidly drying volatile plastic material may be used. The thermoplastic material will set instantly upon the removal of heat. As illustrations of thermoplastic materials, I may employ uncured rubber which is compounded with curing ingredients and anti-oxidants or uncured rubber treated with an anti-oxidant. As a highly volatile coating material I may use celloidin dissolved in an alcohol ether mixture or collodion dissolved in the same mixture. The coating material used, whether thermoplastic or rapidly volatile, should preferably be of such a character that it will produce a coating which is flexible, tough, and possesses substantial tensile strength.

The product claims are presented in a divisional application for Magazine or the like, filed June 13, 1942, Serial Number 446.925, allowed September 10, 1942.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral I0 designates the cover sheet of the magazine, which cover sheet is foldable upon a transverse line II, providing cover leaves I2. This cover sheet has a reinforcing coating I3 applied to its front or inner face, adjacent to the folding line II. The coating I3 is preferably in the form of elongated or elliptical areas, providing with the sheet reinforced coated areas I3 of the same shape and size as the coating. These reinforced coated areas I3 straddle the folding line II and staples I4 pass through the reinforced coating areas I3. The coating I3 is also applied to the leaf sheet I5. 'Ihe coating is applied to the outer or back face of each leaf sheet, at the folding line II and straddles this folding line. This is preferred so that the coating will not be visible upon the inner face of the center leaf sheet, which is usually employed to carry a full-page advertisement." The coating I3 upon the leaf sheet I5 provides reinforced coating areas I3', corresponding in shape and size with the coating I3. The leaf sheet when folded upon its transverse line I I produces the leaves I5'. The reinforced coated areas of the leaf sheet I5 straddle the folding II', as shown. As clearly shown in Figure 4, the reinforced coating areas I3 are arranged in spaced groups, and the areas in each group are in substantial alignment, and the staples I4 pass through the reinforced coated areas and the ends of the staples are bent down over the center leaf, as shown.

As stated, the plastic material is printed upon the sheet to provide the coating. When a thermoplastic material is used, such thermoplastic material is kept in a molten condition in a tank I which is suitably heated. An applicator roll I'I applies the heated molten thermoplastic material to raised type or portions I3 formed upon a printing roll I9, having a blank pressure roll arranged near and opposite the same. The rolls I'I, I3, and 2li are kept suitably heated so that the thermoplastic material is maintained in the liquid condition until printed or coated upon the sheet to produce the coating I3. The sheet is passed between the rolls I 9 and Z and the travel 0f the sheet and the travel of the roll I9 and the location of the raised portions i8 are such that the coating I3 will be formed upon the sheet adjacent to and straddling the folding line I I, when the sheet is subsequently folded transversely upon this line. The coating I3 is applied to the inner or front face of the cover sheet le, as explained, while the coating I3 is applied to the rear or outer face of the leaf sheet I5. The web of paper after having the coating I3 printed thereon, which instantly sets, is then fed between the pairs of printing rolls 2l, whereby one or both faces of the pairs of connected leaves are printed, as is Well known. The web is subsequently severed at intervals to provide the separated pairs of connected folded leaves. All leaves printed upon one web of paper contain the same subject matter, and this is true whether the leaves are cover leaves or inner leaves. When the leaves in each pair are folded, the coating I3 will be arranged to straddle the folding line, producing the reinforced coated areas. Different pairs of folded inner leaves are assembled within a pair of cover leaves to produce the magazine, and the reinforced coated areas are arranged in groups, and the coated areas in each group are in alignment, and the staple I4 is passed through all of the re inforced coated areas in each group. I contemplate applying the reinforcing coating upon all of the inner pairs of folded leaves or I may apply the same only to the center inner folded pair of leaves, with the reinforcing coating applied to the pair of folded cover leaves. As shown in Figure 4e, the coating I3 is applied to the inner face of the cover leaves I2 and to the outer or back face of the center inner leaves I 5 only. The staples iii pass through the coatings or reinforcements, as shown.

If a highly volatile coating material is used, the same may be applied to the printing roll I9 by the roll Il, but elements I5, Il, I9, and 29 would not be heated.

While I have shown the coating as embodying spaced areas, the invention is not restricted to this feature as the coated area may extend throughout the entire width of the sheet.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape. size, and arrangement of parts may be resorted to, and that changes in the order of the steps of the method may be made without departing from the spirit of my invention or the scope of the subjoined claims.
